Reservoir Design and Operation
• What is the optimum size of the reservoir to meet a given demand
• How best can we operate the reservoir in the face of uncertainty of inflows
History provides a valuable clue to the future

Real-time Operation for Flood Control
Water level at A: Function of rainfall in the catchment upstream, evaporation, infiltration, storage, vegetation and other catchment characteristics.; Can be controlled by operation of upstream reservoirs
